Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Effects on fertility
Description of key information
Read across from the RIVM decision from 23 October 2007(BMS071023.03) for Aluminium-magnesium-zinc-carbonate-hydroxide (EC 423-570-6).
Effect on fertility: via oral route
- Dose descriptor:
- NOAEL
- 605 mg/kg bw/day
Additional information
Based on the RIVM decision from October 23, 2007 (BMS071023.03) for analogue Alcamizer P93 (Aluminium-magnesium-zinc-carbonate-hydroxide, EC no. 423-570-6), the available data for the aluminium ion (NOAEL AL3+ >52 mg/kg bw/d) and the Al content of the registered substance (8.6%) were used to calculate the NOAEL for Magnesium-aluminium-hydroxide-carbonate. The same approach as for Alcamizer P93 was used to derive the endpoint, i.e. Al-NOAEL *100/Al content. In the RIVM decision, magnesium ions are stated to be not toxic to fertility.
Short description of key information:
NOAEL 605 mg/kg bw/d (in analogy to RIVM decision for Alcamizer P93, dated 23 October 2007, BMS071023.03)
Effects on developmental toxicity
Description of key information
NOAEL 151 mg/kg bw/d (in analogy to RIVM decision for Alcamizer P93, dated 23 October 2007, BMS071023.03)
Effect on developmental toxicity: via oral route
- Dose descriptor:
- NOAEL
- 151 mg/kg bw/day
Additional information
RIVM decision for Alcamizer P93, dated 23 October 2007, BMS071023.03)
Based on the RIVM decision from October 23, 2007 (BMS071023.03) for analogue Alcamizer P93 (Aluminium-magnesium-zinc-carbonate-hydroxide, EC no. 423-570-6), the available data for the aluminium ion (NOAEL AL3+ <13 mg/kg bw/d) and the Al content of the registered substance (8.6%) were used to calculate the NOAEL for Magnesium-aluminium-hydroxide-carbonate. The same approach as for Alcamizer P93 was used to derive the endpoint, i.e. Al-NOAEL *100/Al content resulting in a NOAEL of 605 mg/kg bw/d for fertility and a NOAEL of 151 mg/kg bw/d for developmental toxicity. The substance is not teratogenic.
Justification for classification or non-classification
In the absence of effects on fertility or developmental toxicity for the analogues, no classification is needed for Magnesium-Aluminium-Hydroxide-Carbonate.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
